Daimler, the world's largest truck manufacturer, will use three-dimensional printing (3D) to produce spare parts, the latest example of how digital technologies are radically reshaping automotive manufacturing and its supply chain. Rather than shipping vehicle parts across the globe, carmakers including BMW and Volkswagen?are experimenting with so-called additive manufacturing. This relies on sending a digital blueprint of a component to a printer which creates parts by using lasers to melt powders into plastic, glass, metals and even ceramics. https://www.entrepreneur.com/article/279090

Compared to existing gold analysis methods which can takes days to get a result, the PhotonAssay delivers accurate results in just a few minutes without generating the toxic waste products which have been problematic in other analysis systems. This new method supported by the CSIRO comes from Australia which is still a major gold producer following the gold rushes of the 1800's. https://blog.csiro.au/finding-gold-rush/

Life Paint is the trade name of a highly-reflective spray paint developed by Volvo to increase the visibility of cyclists during trips after dark.

Although initially developed for the use of cyclists, it could also protect pedestrians.

A new patent reveals Amazon's plans to deploy "air fulfillment centers" (AFCs) that would each act as a flying warehouse from which drones could deliver goods to customers. These AFCs would hover over areas where demand is expected to increase for certain products at a certain time for example at a sporting event. https://futurism.com/a-flying-warehouse-new-amazon-patent-reveals-the-potential-future-of-retail/?
